Teacher B.T. Cates is arrested for teaching Darwins theories. Famous lawyer Henry Drummond defends him; fundamentalist politician Matthew Brady prosecutes. This is a very thinly disguised rendition of the 1925 Scopes monkey trial with debates between Clarence Darrow and William Jennings Bryan taken largely from the transcripts.
